PENCIL.

SPECIFICATION forming part of Letters Patent-No. 481,100, dated August16, 1892.

Application ledJ'une 6, 1892. Serial No. 435,695. (No model.)

To a/ZZ whom, t may concern:

Be it known that I, CLAES WVM. BoMAN, of the city, county, and State ofNew York, have invented certain new and useful Improvements in Pencils,of which the following is a specification.

The pencil to which my invention is directed is one intended to -becharged with a number of lead points or short lengths of lead,

1o which can be successively used as occasion demands. This, I am aware,is not broadly new. The automatic pencil and stopgage pencil, which havebeen for years on the market, can be used for that purpose, and

as a matter of fact in the daily use of such pencils the lead sticks notinfrequently break up into short lengths, which are held in thelead-receptacle and can be protruded therefrom for marking purposes justas though 2o they were a single long lead stick instead of being shortpieces. p

What I have in view is a cheap and efficient form of pencil containing alead receptacle or magazine which is self-closing, so as to retaintherein the lead points with which it is charged and which is adapted tobe opened by a suitable instrument to permit the withdrawal of theselead points one at a time. This withdrawing-instrument in my pencil isthe tip or grasping device which holds the lead point for writing ormarking purposes, the tip being removable and being formed like nippers,which will not only open the self-closing end of the magazine, but will3 5 receive and takehold of the lead point nearest to it in the magazinefor the purpose ofwithdrawing it therefrom. The lead point when thusgrasped is held in the tip in position for writing purposes. All that isneeded after that is to withdraw the tip from the magazine and to fit itpoint outward upon the sheath or body of the pencil. The pencil willthen be ready for use.

The nature of the invention and the manner in which the same is or maybe carried into eifect will be understood by reference to theaccompanying drawings, in which- Figure 1 is a view of a pencilembodying the invention. Fig. 2 is a view of the tip detached. Fig. 3 isa longitudinal axial section of the pencil on line 3 3, Fig. 1. Fig. 4is a View, partly in section, of the pencil when the tip is reversed andinserted in the self-closing mouth of the lead receptacle or magazine,so as to expand the same and to receive the foremost lead point in themagazine. Fig. 5 is a longitudinal axial section of a modified form ofpencil. Y 1

The pencil case or sheath A can be of any suitable form and material.Within it is the 6o tubular receptacle or magazine d, intended toreceive within it a number of lead points or short lengths of lead Z,introduced point foremost into it from the front end, at which end ithas a self-closing mouth, formed in this instance of a split sheet-metaltube b on the prolongation of the receptacle a, having a bell-shapedcontracted mouth which can be spread open by aninstrument inserted init, but which normally is closed against the 7o escape of the leadpoints. Upon the front end of the pencil is tted a removable tip B, ymade of hard rubber, brass, or other suitable sheet metal or othermaterial. This tip has jaws which will grasp and hold a lead pointinserted between them, and which can also be inserted whenever desiredinto the bell-mouth of the tube b to open the same and in that positionto receive and withdraw from the magazine the foremost lead pointtherein. 8o I am not limited as to the particular construction of thetip. It may be variously fashioned and constructed for the purposesindicated. I prefer, however, to construct it substantially on the planexhibited in Letters Patent to Singleton, No. 3I5,865, of July 20, 1886,for rubber-tip attachment for lead-pencils, comprising two jaws pivotedor equivalently connected at a point .fr between their ends to form ineffect two pairs of jaws c d, vso con- 9o nected that the closing of theone set will tend to open the other set, the jaws c being to receive thelead and the jaws CZ being to tit on the pencil-sheath, and the jaws cbeingin addition tapered at the front, so that they will form a conicalY nozzle which can enter the bell-mouth of the tube b and can then beexpanded to open that mouth. 'IVhen the tip is in the position shown inFig. 1, the jaws d are on the stem or sheath A, and when thus roo placedare spread apart with the result of closing the jaws c firmly on thelead point insorted between them. When this point is used up and it isdesired to get another point, the tip is removed from the pencil and isreversed, and, the pencil being held front end downward, the conicalnozzle of the tip is inserted in the bell-mouth of tube b, and is thenexpanded by pressing together the outer jaws (l, with the result ofopenin g the magazine and permitting the foremost lead point therein todrop down in between the jaws c. The parts in this position are shown inFig. 4. Then releasing pressure on the outer jaws d, the inner jaws cclose upon the lead point therein, the mouth of the tube b closes, andthe tip is Withdrawn, carrying with it the lead point, and is thenreplaced upon the pencil in the position shown in Fig. l.

In the pencil represented in Figs. land t the lead points are introducedinto the magazine from the front end ot' the pencil.

In the pencil shown in Fig 5,l1owever, they are intended Ato beintroduced into the magazine from the rear end of the pencil, for whichpurpose the magazine at that end has a selfclosing mouth formed by atube b', similar to the front tube Z).

In this pencil it is intended that the tip shall take its lead pointsfrom the front tube D, as before, but manifestly the magazine can beclosed permanently at the front end and the lead points can be bothintroduced into and withdrawn from the magazine by the rear tube b. Thisremark applies to either form of pencil shown in the drawings; but insuch case instead of arranging the lead points in the magazine butt-endforemost, as represented in the drawings, they should be arrangedtherein point foremost.

The tip shown in Fig. 5 is similar in general construction to that shownin Figs. l to 4; but as it is intended to be inserted into the pencil itis modified in shape accordingly, so that it will enter and iit a socketA', formed for its reception on the front end of the pencil-sheath. Inthis tip I insert ablock of rubberrbetweeu is seated in its socket thefront end of the.

socket, as shown, will extend beyond the pivotpoint a: and upon the jawsc, thus positively closing them upon the' lead.

The pencil shown in Fig. 5 is provided with a removable rubber tip andpoint-protector P, which can at will be placed either upon the rear endof the pencil to cover the magazine-opening at that point, or upon thefront end of the pencil to cover the tip when the latter is not in use.

Having now described my invention and the best way known to me ofcarrying the same into effect, I state, in conclusion, that I do notlimit myself to the special details of construction hereinbefore setforth, since manifestly the same can be varied in a number ofparticulars without essentially departing from the invention; but

What I claim herein, and desire to secure by Letters Patent, is

l. A lead-pencil provided with a lead receptacle or magazine having aself-closing mouth and a tip adapted to open the magazine and to receivetherefrom one of the lead points contained therein, substantially ashereinbefore set forth.

2. A lead-pencil provided with a self-closing lead receptacle ormagazine, in combination with a removable and reversible tip adapted toopen with its lead-holding end the self closing mouth of the magazineand to take and withdraw therefrom one of the lead points containedtherein, substantially as and for the purposes hereinbefore set forth.

In testimony whereof I affix my signature in presence of two witnesses.
